Application filed August I6, 1905. Serial No. 274,494.

a citizen of the United States of America, and resident of Porter,Porter county, Indiana,

have invented acertain new and-useful Imrovement in Safety-Razors, ofWhich the lollowing is a specification.

' vide an improve My invention relates to safetyrazors, and contemplatesan improvement on the forms of razor shown in my priorap lication No.263,715, filed June 5, 1905, an No. 266,881 filed June 24, 1905. v

Obj ects of my present invention are to pro construction and arran ementwhereby the head of the blade-hol er may consist of a casting suitablyjoined to the edge of a sprin y sheet-metal portion,"the said s riny-meta portion being adapted to hold t e b ad'e firmly up surface of thesaid casting proved construction and arrangement where:

y a double-edged blade may be inserted endwise in the razor withoutdanger of the blade slipping sideways and injuring one; of

its edges; ?to provide an improved construc-' tiori and arrangementwhereby the lprojecting end-portionsiof a double-edged b ade can be morereadily and firmly grasped by the thumb and forefinger, for the urpose'of removing the blade from the lade-holding member; to provide the heador holder with a slidin ing the' ladei and features of im crease thegenera ability of a safety razor of this character. v I,

c To the foregoing and other useful ends, my invention consists inmatters hereinafter set forth and claimed In'the accompanyingdrawings,Figure [is a side elevation of a safety razor embodying the principlesof my invention.

As thus illustrated, my invention comprises a combined guard andblade-holder A,

i a blade B,

and handle 0. The said combined guard and blade-holder can be formed ofone on the flat seat or top to provide an 1II1* rovement tending to in'-integral piece of metal 1, stamped and pressed or otherwise given thedesired shape and construction, and a casting 2. As shown, the saidcombined blade-holder and guard constitutes the head of the razor, andis rigidly secured or united to the upper end of the handle C.Preferably, the said head or portion of the razor thus made in part offstantially flat and horizontal portion a ada ted to serve as a seat orbase upon which the lade B may restflat-wise. At each end,

j ecting flanges or edge-portions a and a the former being at the frontand the latter at the rear oftherazor. Consequently, the portions 0/ areseparated from the portionsa, by notches or recesses a At its rear, thehead A is formed with an upwardly and forwardly projecting foot orspringyclamping portion a, the same being adapted to reach upwardly andover and exert a yielding pressure upon the up or surface 'ofthe. bladeB. In this Way, t e said blade-is held removably in place by springypressure, the spring tension, however, being of .such character that theblade can be readily removed. The edge 3 of the portion 1 is adapted tobe inserted endwise and retained in the groove 4 in the portion 2. itsforward edge, the head A is provided with a guard having teeth a, thisguard being of any suitable known or approved formation,that is, toothedor comb-like character.

As shown, the blade B is provided with parallel sharpened edges 6, andalso with projecting end- 'ortions'or tangs 5. When the blade is adusted in place, tangs b accurately fit the recesses or notches and itWill'also be understood that the accurately fits the space between theflanges or edge po'rtions at oppositeends of theseat or base a.Furthermore, the parts are so relatively formed and so proportioned,that the blade is held in place with one of its-edges ,properlypositione the usiialor suitably formed teeth a With can be convenientlygras ed by the thumb and forefinger, and by a s ight upward presspringyfoot or clamping springy sheet metal is provided with a sub it may be ofthe usual these lugs or 7 blade is preferably of such a length that italong the guard having the portion a is provided with upwardly proioothis arrangement, one of the lugs or tangs b sure, just suflicient toslightly flex the v portion a, the end normal position, the blade canthen obviously 3 be readily withdrawn from under the springy' foot orclamping portion a Also, with this construction, the blades can bereadily inserted in place, it being only necessary to grasp the blade atone end and then insert its other end under this s ringy portion a, andto then shove the blade along until its two end-portions snap into placeunder the pressure of the said spring portion. When a blade is beinginserted or removed, the proj ection 5 on the end of the blade engagesthe groove 6 and thereby prevents lateral displacement. In other words,these small rounded projections slide in the grooveone at a time, of"course, depending on which way the blade is movingand thus guide theblade into and out of place in the holder. The groove 6 may be founduseful or advantageous in other ways. Obviously, the construction issuch that the blade is'removable independently of all other parts, andin such a way that the removal is accomplished without even mani ulatingany other parts of the structuretlat is to say, the blade is removableand insertible by simply holding the handle C in one hand and graspingone end of the blade with the other hand. In fact, the entire razorcomprises but two relatively removable members,to-wit, the combinedhandle and blade holder and guard, the same being all in one part, andthe'blade, which latter is, of course, in one piece. The blade whenremoved leaves the 10ld61 without movable arts-that is, parts which mustbe adjusted when the blade is replaced, and the blade alone is removed.After the blade is withdrawn, there are no other portions to be takenapart or to be moved or manipulated in any manner Whatsoever.Consequently, owing to the extreme simplicity of the razor, it can becheaply manufactured, and can ';'.be easily taken care of.

Notwithstanding theextreme simplicity of the structure, the r I find,thoroughly efiective, and satisfac ory for the purpose for which it isintended. Of course the spring jaw I can be made removable from thecasting, but this is not necessary as far as the use of the razor andthe removal and insertion of the blade is concernedat least, not whenthe tangs or handles b are used or maple long enough. Obviously,however, if suc is for any reason desirable, the spring iaw Z canberemoved before removin' the b ade. Also, the blade can be inserte inplace, and the s ringj aw can then be inserted to hold the b ade uponits seat. I do not, therefore,

limit myself to the exact construction shownand described.

It will be seen that the portion 0. provides blade.

overhangin portions. which bear upon the top of the 'lade to prevent thelatter from rising. portions which hold the lade against ed ewisedisplacement in any direction.

said overhanging means or portions can be located in any suitablemanner, and upon any suitable portions of the holder, as, for example,upon a rearward extension of the holder. The said upstanding andoverhang ing portions are comprised in the instrudisplacement upon theholder. It is by relative movement between these retaininginstrumentalities that the blade. is releasably uncovered, leavingitfree to drop or be lifted out of the holder. The said upstanding lugs orportions are disposed in position to engage the corners, orsubstantially at the corners of the rectan uiar blade, the holder beinalso substantia y rectangular in form. A s iding connection 1s providedby which the relative movement between the retaining instrumentalitiesin a horizontal direction is effected for the purpose of releasablyuncover ing the blade. By movement in ahorizontal direction, I mean amovement in the plane of the blade, or substantially in the plane there-The lugs a and a lprovide upstanding V mentalities for holding the bladefixed from of, or in a plane substantially parallel there with. Asshown, the retaining instrumentalities comprise overhanging portionswhich are adapte to slide ina direction parallel with the length oftheblade, but this may be varied without de arting from the spirit of myinvention. he edge 3 is slidably mounted, and when moved causes theoverhanging means to releasably uncover the portions provided by thespring member a are all integrally connected, orv joined together,inasmuch as the said member is composed of an integral piece of sheetmetal; but this may also be varied without departing from the spirit ofmy invention.
